WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 688,248, dated December 3, 1901. Application filed February 25,1901. Serial No. 48,870. (No model.)

To all whom it may concern.-

Be it known that I, CLARK HOGARTH, a citizen of the United States, residing at Wayne, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in WVashing-Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same,reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to washing-machines, and has for its object an improved machine for washing clothes and heating water and keeping the water hot with which the washing is done.

The machine consists substantially of a double-bottomed vessel arranged with a chamber between the two parts of the bottom. \Vater is introduced into the chamber between the two parts of the bottom and also into the interior of the machine, where the clothes to be treated are held. Heat is applied to the external wall at one side of the middle line and somewhat above the lowermost part of the chamber, and a constant circulation of water is produced through the chamber, with overflow on one side into the interior of the machine and inflow on the other side into the chamber within the concave, and arranged to oscillate therein is a rubber.

In the drawings, Figure 1 is an end elevation of the machine. Fig. 2 is a vertical crosssection. Fig. 3 is a vertical longitudinal section. Fig. 4 shows a portion of the bottom of the oscillating rubber. Fig. 5 shows a portion of the inner shell of the machine, showing the holes through which the water pours from the heating-chamber into the scrubbingchamber.

A indicates the outer part of the machinebottom, and B indicates the inner part thereof. The two parts are separated by a space and have between them a chamber used for the heating of the, water that is employed in washing. The outer part A may be of any desirable shape, preferably, however, arched and somewhat eccentric to the arch of the inner part B. The inner part is arched concentric with a point 0 on the end walls of the casing. The end Walls are nearly semicirculain; The walls are preferably made of metal and are stayed along the upper edges by frame-pieces a, Z), and c and d. The heatingchamber 2 lies outside of and under the scrubbing-chamber and is somewhat crescentshaped, with the points of the crescent directed upward, and one of the points enlarges into a chamber 2, which is a condenser for steam generated by heating the washing-water. Steam generated in the heater is gathered in the condenser 2 and held from escape into the laundry-room. Through the wall which divides the heating-chamber from the washing-chamber are two rows of holes, one row 2* situated somewhat below the top of the crescent on the condensation side, which is also the heating side of the chamber, and the other row of holes 2 a corresponding distance below the opposite point of the crescent. The inner surface of the scrubbing-chamber 3 is provided with bars 3 or ribs that extend along the surface parallel with the axis of the partial cylinder formed by said wall. These ribs or bars 3 serve to hold the clothing in place under the scrubber or movable Washboard.

The scrubber consists of an arched segment of a cylinder, hollow, provided on its outside with scrubbing appliances, and pierced through its walls with a large number of perforations. The ends are closed in,and on the inside of each end there is provided a pocket 4, in which is inserted the end of an actuating-lever 5, and the lever is secured in said pocket. The upper part of the scrubbingcylinder is open and the edges are held together by bars 4:. The scrubbing-cylinder itself is held by a bent bail, the cross-bar 5 of which passes horizontally across the machine through the two levers 5 and outside of each lever bends vertically upward and continues upward to the upper surface of the side rail a. It is here again bent at right angles and each end continues along the rails, one rail continuing along the rail 61 and the other along the rail b to near each of its outer ends, where it is again bent at right angles style of which may be used.

and where each end engages through an eye inserted in the side rail. The two eyes 5 and 5 hold the scrubbing-cylinder from sliding movement with respect to the side bars a and b, but the scrubbing-cylinder can swing on the cross-bar 5 as a center. It can also swing in the eyes 5 and 5, and consequently is capable of an oscillating movement around the bar 5 or a substantially vertical movement in the scrubbing-chamber, the slight curve of this movement being so small that the movement is practically vertical and the scrubbingcylinder can be oscillated over the articles interposed between itself and the bottom wall of the scrubbing-chamber, whether the space between them be small or great. On the outside of the scrubbing-cylinder, parallel with the longitudinal axis, are a number of scrubbing o' r rubbing bars. Preferably these bars are'made from cables or twisted wire W.

Underneath the machine and at one side of the central line isplaced the burner S of a gasolene-stove. There may be one burner or several burners, as may be necessary, to heat the water to be used. The burneris fed from a tank T and in arrangement does not differ from ordinary gasolene-burners, any suitable As will be seen in Fig. l, the water-heating burner'is placed somewhat toward one side and not'quite at the center of the machine. The water directly above the burner is heated thereby and rises on that side, becauseof its smalle'r'specific gravity, toward the chamber 2, the cooler water from the other side of the machine flowing in to take the place of the rising'i 'water. Thelevel of the water being above'the holes 2 2 the rising hot water fiows slowly through the holes 2?, mingling with the cooler water inthe scrubbing-chamber 3',"fr'om whence it flows through the holes 2 and'idesce'nds to take the place of the rising hot water just over the burner. The surface of the hot water over the burner is inclosed by the walls of the chamber 2, so that p the hot'water is prevented from supersaturatinglthe'air of the laundry room with its -vapor'. The water running in'to the heating-chaxixberhas been through the soiled clothes and contains some dirt, and the heaviest of this dirt is allowed to settle and sepaher provided with double walls at the bottom and ends, forming-a continuous chamber therebetween extending up the ends and across the bottom, the inner walls of the sides having holes formed therethrough beneath the normal level of the water, and a source of heat adapted to heat the water between the double walls at one endof said continuous chamber, said continuous chamber being closed at its upper end above said source of heat.

3. In a washing-machine, in combination with a curved plate forming the bottomofa 7 scrubbing-chamber, a second curved plate below the first forming the bottom of a heating.-

chamber, the first of said plates being provided with a row of perforations at one side near the top thereof for the inflow of heated water from the heating-chamber and with a second row of perforations; atthe opposite side and near the top thereof for the outflowv of water from the scrubbing-chamber into the heating-chamber, whereby when heat is ap-- plied to the heating-chamber, acirculation of into the scrubbing-chamber and is required 0. Water is produced that flows from above down M to pass entirely across the scrubbing-ch'amher before, reentering the heating-chamber,-

substantially as described.

In testimony whereof I sign this spe-cili cation in the presence of two witnesses.

CLARK HOGAR'IH.
